How do I find a 26" Rad. ? car only had motor and Tranz.
No, Rearend, no springs, no interior, no Radiator . Missing so much but worth the resto I think .
You can find OEM style out there onthe internet or go with something like this (you need to call for the 26”)

Barracuda (66-69) 22" Small Block Radiator
